Reciprocating Switch Sleeve for Residual Gas Pressure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of fluid-driven devices, such as guns and riot control guns, often face difficulties in disassembling the devices due to residual high-pressure gas, which can obstruct the connection mechanism.
Innovation Solution
A reciprocating switch for high-pressure fluid lines is designed with an inlet and outlet switch body, communication ports, and a sleeve that allows for quick switching of fluid flow and release of residual pressure, enabling easy disassembly of fluid-driven devices.

Engineering Contradiction Analysis
1Stress or pressure
If a pressure-reducing valve is used to supply high-pressure gas to fluid-driven devices, then the device can operate with sufficient pressure, but residual pressure remains in the device after use which obstructs disassembly
Solution Approach 1:
The switch body is segmented into multiple functional sections: an inlet chamber for receiving high-pressure gas, an outlet chamber for supplying reduced-pressure gas, and a communication chamber that can selectively connect these two chambers. This segmentation allows independent control of pressure reduction and flow direction, enabling the release valve to vent residual pressure without affecting the main pressure reduction function.
Solution Approach 2:
The communication chamber acts as an intermediary between the inlet chamber and outlet chamber. It provides a controlled pathway for gas flow and allows the release valve to access residual pressure in the outlet chamber without directly connecting to the high-pressure inlet, thereby safely managing pressure transitions during disassembly.
2Ease of operation
If the trigger is pulled to release residual gas pressure before disassembly, then the connection mechanism can be disconnected, but users may not be aware of this procedure causing disassembly difficulties
Solution Approach 1:
The release valve is designed to be automatically accessible and operable without requiring users to understand complex procedures. The valve's position and operation are intuitively linked to the disassembly process, allowing users to release residual pressure through a simple, self-evident action rather than requiring knowledge of a separate trigger-pulling step.
Solution Approach 2:
The release valve provides a preliminary action to vent residual pressure before the actual disassembly of the connection mechanism. This preliminary pressure release ensures that the subsequent disassembly can proceed smoothly without resistance from trapped gas, preventing the obstruction problem before it occurs.
3Ease of operation
If a reciprocating switch mechanism is added to control fluid flow and release pressure, then residual pressure can be quickly released for easy disassembly, but the device complexity increases
Solution Approach 1:
The release valve functionality is merged into the existing switch body structure rather than being added as a separate external component. The release valve shares the communication chamber and structural elements with the main pressure reduction mechanism, allowing dual functionality (pressure reduction and residual pressure release) within a unified structure that minimizes overall complexity.
Solution Approach 2:
The communication chamber serves multiple functions: it acts as a passage for normal gas flow during operation, a chamber for pressure equalization, and a access point for the release valve during disassembly. This multi-functionality reduces the need for separate dedicated structures for each function, thereby limiting the increase in device complexity while achieving quick pressure release capability.

AI summary
A reciprocating switch for high-pressure fluid lines comprises an inlet switch body, an outlet switch body, a first communication port, a second communication port, and a sleeve. The inlet switch body has an inlet at one end and a closed end at other end with an inlet chamber therebetween that communicates with the inlet. The outlet switch body extends from the closed end of the inlet switch body and features an outlet at its outer end with an outlet chamber therein that communicates with the outlet. The first and second communication ports communicate interior and exterior of the inlet and outlet switch bodies, respectively, and the sleeve is reciprocable and fits over outer surfaces of both switch bodies with an annular groove in its inner wall communicating with both communication ports or only the first communication port.
